Nvidia Linpack: CUDA Accelerated Linpack Benchmark
NOTE: For Nvidia GPUs only.
This test is implemented to run separately on each node using all CPU cores and all GPUs with about 80% or less of memory. Two parameters must be specified: Mem (GB) and Mem (%). Mem (GB) is the total memory in Giga Bytes on each node and Mem (%) is the percentage of total memory used in the test. This test does not give the cluster wide performance but it exercises CPU, GPU, and memory at the same time and it provides another set of numbers used to compare the relative performance among the cluster nodes. The amount of memory required is set to auto by default. This runs each node at the specified percentage of the memory available. For example, using auto and 80% a 2GB node uses 80% of 2GB while a 16GB node uses 80% of 16GB. The amount of memory used on any management node is adjusted to allow for increased memory consumption on management nodes.
